What is IBM DataPower Gateway?

IBM DataPower® Gateway helps organizations meet the security and integration needs of a digital business in a single multi-channel gateway. It provides security, control, integration and optimized access to a full range of mobile, web, application programming interface (API), service-oriented architecture (SOA), B2B and cloud workloads.

Hypervisors that the IBM PureApplication System manages allow only eth1-3 to be used for DataPower service configuration

eth0 is used by IBM PureApplication System management

All other hypervisor environments allow eth0-3 to be used for service configuration

Deployment on stand-alone VMware hypervisors

Configure the appliance to run inside the virtual machine

Start Commissioning

Login to the appliance

Enable Secure Backup Mode

Enable Common Compatibility Mode

Create new admin password

Run the Install Wizard

Step 1 - Confirure network interfaces

Step 2 - Configure network service

Step 3 - Define a unique system identifier for the appliance

Step 4 - Do you want to configure remote Management access

Step 5 - Configure a user account that can reset passwords

Step 6 - Configure the RAID array

Save the current configuration

Configure the appliance to run inside the virtual machine

Setup the virtual machine

Install VMWare player

Inport the OVA file of the virtual applicance

Use the below configuration

Memory

Minmum: 4 GB

Required: 8GB

Processors

Minmum: 4 GB

Required: 8GB

Network Adapter

Insure that one of the adapters eth0 is Host-only

Start Commissioning

Login to the appliance

login: admin

password: admin

Enable Secure Backup Mode

Secure backup mode supports the creation of a backup to restore the complete configuration of another DataPower® Gateway. The creation of a secure backup is available only when secure backup mode is enabled. Generally, secure backup mode is enabled during the initial firmware setup of the DataPower Gateway

Confirn Enable Secure Backup Mode

Enable Common Compatibility Mode

When the DataPower Gateway is in Common Criteria Compatibility mode, it forces several settings to specific values. These values are required and enforced at restart. Common Criteria Compatibility mode affects audit log policies, password policies, and includes a group of default rules and actions.

Create new admin password

Please Enter New Password to be used in next login

Run the Install Wizard

Step 1 - Confirure network interfaces

Do you want to confirure network interfaces

Do you want to confirure network interfaces answers to do

Start configuring the first network interface

Enable the DHCP

Don't configure the rest network interfaces

Step 2 - Configure network service

Step 3 - Define a unique system identifier for the appliance

Sometimes there is a need to have an identifier that is unique per DataPower device. Typically the device serial number is taken for these purposes.

Note: Give any appropriate unique system identifier.

Step 4 - Do you want to configure remote Management access

These configuration require the IP address of the local interface that manage the appliance.

Do you have this information? [y]: y
Do you want to enable SSH? [y]: y
Enter the local IP address [0 for all] : 0
Note: In case you provide specific IP earlier, Provide same IP as provided earlier.

Enter the port number [22]:
Note: Just enter to accept default or write your needed port

Do you want to enable WebGUI access [y]: y

The WebGUI is one of the graphical user interfaces that the DataPower Gateway provides. The Blueprint Console is the one of the graphical user interface (GUI) for the DataPower Gateway. The Blueprint Console allows you to create and manage patterns and tenants.

Step 5 - Configure a user account that can reset passwords

Step 6 - Configure the RAID array

Save the current configuration

Access the configured device

Show int

The show ip interface command provides tons of useful information about the configuration and status of the IP protocol and its services, on all interfaces. The show ip interface brief command provides a quick status of the interfaces on the router, including their IP address, Layer 2 status, and Layer 3 status

Network Deployment: Contains both Liberty and Full Profile technology stacks. The Liberty Stack includes all of Base plus the ability to Cluster JVMs and to organized them through a collective and a single Administration Center. Ability to have assisted life cycle with the intelligent management components of full profile. Plus licensing for all of WebSphere Extreme Scale (object grid caching)

It happens because the docker client (on macOS or Windos 10) allows you to sign in with your email address and password. If you sign out and sign in with your Docker Username and password everything will work. So here's a better description of the issue

DescriptionWhen trying to pull images from the Docker registry docker: Error response from daemon: Get https://registry-1.docker.io/v2/library/hello-world/manifests/latest: unauthorized: incorrect username or password. This happens if you sign in to Docker using your email address instead of your username.

In the simplest terms, git pull does a git fetch followed by a git merge.

You can do a git fetchat any time to update your remote-tracking branches under refs/remotes/<remote>/.

This operation never changes any of your own local branches under refs/heads, and is safe to do without changing your working copy. I have even heard of people running git fetch periodically in a cron job in the background (although I wouldn't recommend doing this).

A git pull is what you would do to bring a local branch
up-to-date with its remote version, while also updating your other
remote-tracking branches.
